Normally studios release brief teaser trailers months before a film comes out and then when the release date is approaching, they show you a bit more of the film, but with the Saw movies, they know that showing you too much might make you realise that it’s actually going to be rubbish, and so they’re just going for lots of flashing images and simply letting you know Jigsaw is returning and there’ll be some more gruesome traps. Take a look at the trailer below to prepare you for the film, which is due in cinemas at the end of October.
